REGENERATIVE COKE-OVEN.

T 0 all whom it may concern:

Be it known that I, IEVENCE COFFEE, a subject to the King of Belgium, and resident of 71 Boulevard dAnderlecht, Brussels, Belgium, engineer, have invented certain new and useful Improvements, in Regenerative Coke -Ovens', of which the following is a specification.

This invention relates to an improved construction of coke ovens with regenerative action, which offers all the advantages of similar known constructions, while doing away with the inconvenience resulting from the reversal of the currents of the combustible gases and flames whereby only half of the ovens are heated at one time alternately; in other words, the improved construction realizes all-the advantages of the regenerative system, while allowing all the ovens to be heated simultaneously along their entire length and in a continuous manner, without requirin to change the direction of the currents. or this purpose, on the one hand, all the products of combustion of the battery are brought to one and the same point whence they are directed at will to the one or the other of two regenerators, whence they pass to the boilers, while on the other hand, the air necessary for the combustion, after having been heated in the one regenerator, is conveyed simultaneously to all the combusby way of example, one form vof construction of the coke ovens according to my present invention.

Figure 1 is a vertical longitudinal section through one of the ovens of the battery. Fig. 2 is a longitudinal section across the side wall., Fig. 3 is a transverse section on line V W Y Z of Fig. 2. Fig. 4 is a horizontal section to a smaller scale on line a: as of Fig. 1.-

Figs. 5 and 6 are detail sections to a larger scale.

' The passage of the gases in the various canals ofthe sidewalls shows nothing particular; it is, in every respect similar to that followed by the gases in other well known systems of coke furnaces with vertical canals and especially in the system described in Coppees United States patent 794662. As amatter of fact the gas evolved from the coal passes in the upper part of the oven through the four openings 1), the gases thus enter the chambers p, whence they pass into the sidewall by the four chambers p, and then pass Specification of Letters Patent.

ing through the openings 1 descend into the partition by 18 flues c of which 9' are in front and 9 behind. The gases thus arrive in the chambers d to ascend eight fiues c four of which are in front and four behind. The two six flues c and pass beneath the floorwhere they depart by fluesf in the front half and by fluesf in the rear half to the collecting channels a, the latter extend along the entire length of the battery and open at the front of the same (to the right hand at Fig. 4) into a special apparatus shown in vertical section at Fig. 5. This apparatus is composed of a cylindrical it g divided into four chambers by means of two vertical partitions h and m, each of which chambers has an opening t. This pit is inclosed at top by means of a mova at Fig. 6, and which is rovidedwith a diametrical partition 0. T is apparatus causes ator r or into the regenerator 1", according as the cap a occupies the position in which the partition 0 coincides with the partition m, or that in which it coincides with the partition it. The regenerators r-and 1" have, as usual, a filling of refractory bricks arranged inthe known manner.

ator the gases issue at. the opposite extremity of the battery into a second pit g which is also divided into four chambers by means of two vertical partitions h and m, each of which chambers has an opening 4,; the pit g is'also inclosed at to by means of a revolving cap with a dlametrical partition. From the pit g the ases pass into a flue -'7c leading to the steam boilers or other apparatus where they are to be utilized. The gases take the following course: The gases pass through the longitudinal canals a", as indicated by the arrows, and arrive at the first apparatus 9-, They enter throu h i into the compartment of this well w ich is connected with the saidcanals, and ascend again as far as to the top of the well; If the position of the bell is such that the diametral partition 0 is placed ,over the partition m of the ,wellythen the gases pass above the partition h, come down a ain through the adjacent compartment an reach from there the regenerator r. They pass through the latter in the direction indicated in the drawingby the arrow and arrive at the second apparatus g currents of gas thus reunited then descend by le cap n, shown separately in section the hot gases to pass either into the regener- After .having passed through the regener into which they enter 1 through that compartment connected with the regenerator 1". They rise in the said compartment as far as to the upper part of the well and, owing to the position occupied by the bell whose diametrical partition is in this case placed on the partition h, they pass into the adjacent-compartment which communicates with canal 76 running to the boilers, etc. The preceding explanation applies to one of the positions of the bell; it may be easy to infer therefrom the corresponding course, when the bell is in its second position.

'The air necessary for the combustion of the combustible gases produced in the coke ovens is conveyed through a pipe Z into the second half of the pit g and passes to the regenerator which -for the time'being does' not have the combustion gases passing through it. After having been heated in the regenerator the air passes to the pit g from which it passes to the hot air channel L whence it rises into the fines L (Fig. 1) which v of hot air.

direct it towards the front and the back ends of the several ovens and whence it is distributed to all the combustion chambers. Slides are provided forregulating the supply When the caps n occupy the positions in which their partitions 0 are situated respectively upon the partitions m and h of the pits g and gthe products of combustion which pass from the fines a are conveyed by the cap 'n into the regenerator 1" and thence to the boilers, while the air passes from the supply pipe Z to the regenerator 1" and thence through the cap n to the channel L and thence to the several combustion chambers, the direction of fiow of gases and air being indicated by arrows in Fig. 4.

When the air, conveyed to'the regenerator 7", has taken up all the heat whichwas stored therein, the caps n are turned through 90 so that their partitions 0 are situated respectively upon the partitions h and m. The combustion gases will then be sent to the regenerator r and thence to the boilers while the air passes to the regenerator. 1*, where it is heated and whence it passes through the channel L to the ovens. The caps n are operated simultaneously by means of anysuitableknown arrangement of mechanism with transmission gear, which is not shown on the drawing.

. Having now described my invention andin what manner the same is to performed,

for the combustion, the two remaining canals r r forming regenerators, a well of four chambers with which the canals communicate, a bell surmounting said well and which causes, at will, the canals a, to communicate with any one of the regenerators and the canal L with the other regenerator, a

second well communicating withthe two re generators at the rear of the furnaces and which causes to communicate, at will, any one of the regenerators with canals leading to boilers, and the other regenerator with the conduit for letting-in cold air.

2. In regenerative coke ovens-of the kind herein referred to, a battery of coking chambers, having five channels located therebelow, said channels extending longitudinally of the battery, of which the two outer ones a receive the combustion gases from the ovens, the middle one L serves to convey the heated air required for combustion to the ovens, while the two intermediate channels 1" r constitute regenerators for alternately taking up heat from ,the combustion gases and imparting the same to the air supply, a reversing valve chamber with four compartments with which said channels communicate by means of which While the one channel a is made to communicate with one of the regenerators, the air channel L is made to communicate with the other regenerator, a I

second reversing valve chamber with four compartments communicating with the other end of the channels whereby the one regenerator is made to communicate with a flue leading to'boilers, while the other'reg enen ator is made to communicate with the atmosphere substantially as described.

In witness whereof I- have. hereunto set my hand in presence of two witnesses.
